简要总结

Severely mutilated anterior primary teeth in preschool children are frequently managed by extraction. However, premature loss of anterior primary teeth has been associated with adverse functional, developmental and psychosocial outcomes, including impaired oral health-related quality of life (OHRQoL), speech concerns and negative self-image.

Prefabricated zirconia crowns offer an aesthetic and durable restorative alternative for compromised anterior primary teeth. Despite increasing clinical use, comparative evidence evaluating zirconia crown restoration versus extraction under equivalent conditions using validated patient-centred, developmental and economic outcomes remains limited.

This pragmatic, prospective, non-randomised controlled clinical study aims to compare zirconia crown restoration and extraction of severely mutilated anterior primary teeth performed under GA in preschool children. Outcomes include OHRQoL, parental satisfaction, child self-image, and speech development.

详细描述

Early childhood caries (ECC) remains one of the most prevalent chronic conditions in preschool children. Management of decayed anterior primary teeth is particularly challenging due to young age, limited cooperation and extensive tooth destruction. As a result, extraction is often selected as a definitive treatment.

However, systematic and rapid reviews have demonstrated associations between premature loss of primary anterior teeth and adverse outcomes, including reduced OHRQoL, speech distortion, altered oral habits and psychosocial impacts. These reviews have consistently highlighted the need for prospective, patient-centred studies employing validated outcome measures and addressing methodological limitations of earlier research.

Prefabricated zirconia crowns have emerged as an aesthetic and durable restorative option for anterior primary teeth. While clinical success and parental acceptance have been reported, direct comparisons with extraction that incorporate patient-centred outcomes and economic evaluation are scarce.

This study addresses these gaps by prospectively comparing zirconia crown restoration and extraction of decayed anterior primary teeth, using validated OHRQoL, parental satisfaction, child self-image and speech development.
